my poor baby

My 6 week old son has a stuffy nose and a lot of saliva in his mouth and it sounds like a wet cough. I took him to doctors yesterday and day before. His vitals and lungs are good. I took him to hospital yesterday and they just told me to use saline drops and suction. I feel soooo hopeless. Has anyone else gone through this with a baby this young ???
